KANAME NO MORI : Keystone Forest Commercial Building/Nori Architects + Takada Landscape Design Co.
Architecture as the “cornerstone” of environmental regeneration— KANAME NO MORI is a new commercial building located in Musashi Hill, Shinagawa-ku, Tokyo, facing the Palm shopping mall. The scheme is expected to be an economic success as a commercial complex, contribute to the revitalization of the area and create a healthy soil, water and air ecosystem. We believe that architecture should play a key role in the regeneration of the environment.
The building is placed on the northwest side, leaving a margin of about 2m with the south side. The second-floor wall is set back 3.5 meters to form a staircase connecting the first, second and roof floors, forming a third-floor space. A three-dimensional path from the arcade to the street behind the building. Additionally, in a triangular space on the north side of the site, an ancient shrine was preserved and restored, and a single-story wooden shrine office was built facing the shrine, doubling as a building management office. This allows half of the tenants to face not only the arcade but also the green channel, which enhances the commercial value of the building. In addition, by creating a multi-level access to the street behind the building and the businesses to the north, new circulations are created and ventilation and daylight are improved within the site.
Exterior works at the base and roof are constructed using the Takata method, which retains and purifies rainfall and recharges groundwater. Scattered mounds of soil are planted with oak, sawtooth, white oak and other saplings. Trees and vegetation will eventually cover the entire site, creating a cool, comfortable, and humid thermal environment. Rainwater flows down the slope and over the path and on the other side. No retaining walls were installed to retain water flow and prevent gutters from clogging. Instead, install L-shaped fittings every 900mm on the top L-shaped angle steel, and use iron wire to fix the thick branches to the L-shaped fittings. The exterior wall directly beneath it is plastered with soil left over from excavations on the site. Rainwater runs down this wall.
The earthquake resistance, fire protection, waterproofing, thermal insulation, air tightness, etc. required for urban buildings are all constructed and met through typical man-made materials such as concrete, steel, and glass. However, the materials used for interior and exterior plastering and exterior wall construction are all natural materials such as soil, stone, charcoal, straw, fallen leaves, and branches. The soil used is excavations left over from the construction process, and branches, twigs, fallen leaves are all produced during the maintenance of gardens and forests. These natural materials were built by hand, without the use of heavy machinery or the installation of an irrigation system. This is a proposal for a new way of building in densely populated cities, where materials are nurtured through the power of nature, life and human hands to become the “building blocks” of environmental regeneration.
